To all whom it may concern:

Be it known that I, ALPHONsUS L. MONA- onAN, a citizen of the UnitedStates, and a plug of improved form whichv is especially adapted forrepairing a puncture or perforation in a hose such as that described.More particularly; the object is to give the plug a orm whic willfacilitate its introduction into the puncture, and which will, operateto insure that the plug will remain in position. The invention consistsin the apparatus and in the process to be described more fullyhereinafter and particularly set forth in the claims.

Before proceedin to a detailed description of the parts, it willacilitate the disclosure to state at the outset that, in the practice ofthe invention, at the point where a puncture or rupture has occurred, Iform a slit or opening which is of suflicient size to admit a plug of aspecial form; I provide a special device for forming the slot andinserting the plu and after the plug is inserted, I rovide a 0 amping orremforcing band w ich is attached around the hose at the plug, if thecondition of the hose appears to necessitate the presence of such areinforcement.

Reference is to be had to the accompany ing drawings forming a part ofthis specification, in whlch similar characters of reference indicatecorresponding parts in all the fig ures.

Fi ure 1 represents a-short section of hose whic has been repairedaccording to the present invention, showing the plug in position,together with the aforesaid clamping or reinforclng band; Fig. 2 is across section taken through the hose at the plug as illustrated in Fig.1; Fig. 3 is a longitudinal sec- .tion taken through the section of hoseat the plug; Fig. 4 is a plan showing the reinforcing and lying fiat ordeveloped upon the flat surface, a portion of the band being brokenaway; and Fig. 5 is a pers ective of a plug such as used in practicing te invention.

Referring more particularly to the parts, 1

represents the portion of hose supposed to have been repaired. At thepuncture or ruptured point, a plug 2 is inserted in the manner to bedescribed hereinafter. The form of this plug is most clearly illustratedin Fig.

5; it is of elon ated or lozenge form, having an elongated ead 3,presenting a convex under side or crown 4 and an annular shoulder 5assing continuously around the ovalshaped body 6 of the plug. This body6 has the form of a flattened cone; that is, it enlarges toward itsupper end or butt end, as illustrated in Fig. 5. In this way the plug ismade to present an elongated or major axis and a reduced or minor axisat right angles thereto.

In man cases a hose repaired as described wi l he sufliciently strong,but if the wall of the hoseat the punctured point is weak or unsound, Iapply to the hose a reinforcing band 18. Thlsband is formed of an elonated strip of light sheet metal having the form illustrated in lig'. 4;at a sritable oint it presents an enlargement 19 having a ozenge-shapedopening 20 which is ada ted to receive the body of the plu as ilustrated in fig. 1. At one end t e strip is formed with an eye 21, andat the other end with a tongue 22 which is adapted to be assed throughthe eye and bent back 11 on ltself, as ilh' strated at 23 in Fig. 1. earthe bending point of the tongue 22, the band is provided with laterallyrojecting cars 24, which are adapted to be olded down 11 on the tongue,as lllustrated most clearly in ig. 2. In this way the band may be fittedand "clamped close to the outer surface of the also tends to prevent anydisplacement of,

the plug if it tends to become loose.

Special attention is called to the fact that after the plug is appliedas illrstrated in I ig. 3, its outer portion being of enlarged diame tertends to prevent any tendency of the plug to work inwardly in theopening. S ecial attention is called, also, to the fact t rat the plugis not of reat width when meas- 11 red circumf'erentia ly of the hose.and hence it can be applied to hose of small diameter having greatcurvature. The plugs will, of course, vary in diameter to sit the kindsof hose with-which they are rsed.

Special attention is called to the conical form of the cavity 6* in theconical bed of the plug and to the manner in which the ottom of thiscavity affords a point for the application of the inserting toolreceiving all the thrnst. The conical form of the cavity favors theinward collapsing of the'wall of the body of the plug, which is incidenttothe insertion of the plug. Attention is also directed to the fact thatthe thickness of the wall of the body of the plug decreases toward itsupper -portion or that: toward the end which Is remote from the holes.In this way I give snfiicient mass and thickness to the red ticed partof the cone which is disposed in the opening or puncture, and at thesame time the-onter part of the wall is fiexible e'no'cgh to. collapsefreely in inserting the p11 g. The p11 g is inserted by means ofa flattool having abl'cnt point.

Having this descn'hed my invention, I claim as new and desire to secureby Letters Patent:

1. A plrg for a punctured'hose having a conical body with an enlargedhead at the redzced end thereof adapted to be forced through the p;nctLre, said body having an enlarged comcal cavity formed in the largeend thereof extending inwardly towardsald head, the bottom of saidcavity being 1.nobstrncted and adapted to receive the entire thrustofthe inserting tool, said cavity forming a space between the insertingtool and the wall of said head.

- 2; A plu for a punctured hose having a conical'bo y with an enlar edhead at the forward reduced end of said ody, said body having a conicalcavity extending into the same mm the large end thereof and forming awall for said body decreasing in thickness gradually toward the largeend of said body, the bottom'of said. cavity presenting a continuoisunobstructed snrface adapted to re- In testimony whereof I have signedmy name to this specification in the presence of two sub scrlbingWitnesses.
